Ideal Sun Conditions:
Terrific taller plant for the late summer garden. Native from eastern U.S. that grows well here too in a medium water-use area. Talls stems with numerous yellow centered, small aster-like white flowers that look similar in appearance to Michaelmas daisies. Propagation by root division in spring or by seeds. Does reseed some. Other varieties are 'Snowbank' only to about 4-5' but with larger flowers, and 'Pink Beauty' with pink flowers.
Use in Garden
Medium water-use mixed bed or border. A tall grass prairie garden. Native plant garden. Western cottage garden. Perfect in a Monet style garden -- it provides the shimmer and the see-through airiness Monet so loved to paint.
Divide the clump after several years. Top dress with 1 inch compost spring and fall. Fall cleanup after frost, or wait until end of winter. I haven't found staking necessary.
